COTTON-GIN ATTACHMENT.

To all whom it may concern:

Be it known that I, GEORGE W. Lone, a citizen of the United States, and a resident of Lindsay, in District 17, Indian Territory,

have invented. a new and Improved Cotton- Gin Attachment, of which the following is a specification.

The invention relates to means for conveying or removing the cotton-seed from the ginbox, and has for its object peculiar, novel, and improved means for the purpose stated, the same being designed for use in place of the screw conveyer commonly employed in the bottom of the seedbox.

The invention consists of the novel pneumatic apparatus hereinafter fully described, shown by the accompanying drawlngs, and pointed out in the appended claims.

In the drawings, Figure 1 is a view of a portion of acotton-gin seedbox with my in-' vention shown applied. thereto. Fig. 2 is a transverse vertical sectional view taken on the line 2 2 of Fig. 1, and Fig. 3 is a similar sectional view taken on the line 3 3 of Fig. 1.

- In the embodiment of my invention an air passage-way A is arranged extending under the seedbox B of a cotton gin. (Not shown.) Between the passageway A and seedbox B, I arrange a suitable case C, having an open bottom D, providing .communication with the air passage-way A, and an open top E, arranged communicating with the interior of the seedbox B, substantially as shown by Figs. 1 and 3. In the case C, I arrange two valves F, arranged one suitably above the other, substantially as illustrated by Figs. 1 and 3, the same being supported along one edge on a rod G.

It is intended to provide the ends of the rods G with suitable bearing-support on the case C, adapting the valves F for swinging action to dotted open position (illustrated in Fig. 3) and for adjustment to horizontal positlon, closing the passage-way H through the case C.

In the case passage-way H, I arrange upper and lower flanges I, against the under side of which the valves F are adapted to upwardly seat, as will be understood upon reference to Fig. 3 of my drawings.

In the preferred embodiment of my invention adjacent valve-cases i are arranged, providing a separating space J adapted for arrangement therein of a revoluble device substantially in the form of a band-pulley K, the pulley being arranged on a shaft L, hav- Specification of Letters Patent.

ing suitable bearing-support on two adjacent cases C, the bearing being indicated by dotted lines in Fig. 1.

Upon reference to Figs. 1 and 2 it will be noticed that the rods are arranged with projectin ends M. The projecting ends of the rods C are provided with fixedly-secured transversely-disposed arms 1 having weights 0 at their free ends, the weights being designed for holding the valves F seated to closing position of the passage way II through the case C. In further carrying out my invention I provide the arms N with noses P, extending them beyond their sup port on the rods G and adapted for engagement by projecting pins Q on the revoluble device or band-pulley K.

In the practice of my invention it is de-- signed to employ forced or induced drafts of air through the passage-way A, the same bein effected through operation of any suitable air-pump or blowerR, located at one .end of the air passage-way, substantially as shown in Fig. 1.

Cotton-gins being well understood I have deemed it necessary for a full understanding of my invention to illustrate same in connection with simply the lower portion of a ginseedbox.

Now it is apparent that upon motion being imparted to the revoluble device K the tappet-pins Q will be carried along into contact first with the nose P, and thereby'lift the weighted end of the arm N. This action obviously will operate, adjusting the upper valve F downwardly and dump the ginned seed accumulated thereupon. It is further apparent that passage of the seed through the case is next obstructed by the lower valve F. Continued rotation of the device K will carry its. tappet-pin Qinto contact with the nose P on the outer end of the operating-rod G of the lower valve F, and thereby operates, adjusting the lower valve downwardly to position, dumping the seed into the passageway A, adapted to be conveyed therethrough to any desired location of deposit by pressure of the drafts of air through the passage-way hereinbefore specified. While the above-described operation of the valves in one case is taking place, it is obvious that the similar valves in the next case are being operated in similar manner by a suitable tappet on that side of the revoluble device K.

I would call attention to the fact thatwith my construction of parts their mode of operation and through provision at all times of one valve serving to cut ofi" upward passageway through the case C the drafts of air through the passage-way A are prevented entrance into the gin-seedbox, and the seed thereby efiectively conveyed away from the gin, as will be understood.

What I claim is- 1. A cotton-gin seed-conveyer, having a passage-way located below the gin, means adapted for producing drafts of air through the passageway, a case providing open communication between the gin and said passageway, a series of valves in the case, means adapted to hold the valves yieldingly seated, and closing the passage-way through said case, and means adapted in operation, for step by step separate adjustment of the valves, to open position.

2. The combination with the seedbox of a gin, of an air passage-way, means adapted for producing drafts of air through said passageway, a case located below the gin-seedbox having intermittently open communication between the air passageway and seedboX, upper and lower upwardly-seating valves in said case, means adapted for holding the valves yieldingly seated, engaging devices fixedly connected with the valves, and means adapted in operation, for step by step separate adjustment of the valves to open adjustment.

3. The combination with the seedbox of a gin, of an air passage-way, means for producing drafts of air through said passage-way, a case located below the gin-seedboX having intermittently open communication between the air passage-way and said seedbox, upper and lower upwardly-seating valves in the case, rods providing support for the valves, the rods projecting outside of the case, weighted arms on the projecting ends of said rods, noses at the supported ends of the arms, and a suitably-supported revoluble device having a tappet thereon, adapted for step-by step engagement with said noses and thereby effecting separate adjustment through the connecting means, of the respective upper and lower said valves.
